Tony,
First of all, it's a night qualification, not a rating. That's a big difference in JAR-world, because it means you don't need a JAR instructor to do the training. Your FAA night instruction will count in full towards your qualification. I did my entire 5 hours with an FAA instructor.
The requirements for the issue of the rating are 5 hours of night flying, of which 3 must be dual, and one of those dual hours must be cross-country. You must do 5 solo take-offs and full-stop landings (which probably takes no more than 45 minutes). The rest can be either dual or solo - most people make up the 5 hours with extra dual time, but if you've already got solo time that'll be fine as long as you meet all the other requirements.
If you've done everything you need to do already, the only thing left is to fill out the paperwork and send it to the CAA, with a cheque of course!. You will need your instructor's signature on the form, though.
